Current state of the driver for the ADP5588/87 only allows partial I/O to be used as GPIO. This support was previously present as a separate gpio driver, which was dropped with the commit 5ddc896088b0 ("gpio: gpio-adp5588: drop the driver") since the functionality was deemed to have been merged with adp5588-keys. This series of patches re-enables this support by allowing the driver to relax the requirement for registering a keymap and enable pure GPIO operation. Signed-off-by: Utsav Agarwal <utsav.agarwal@analog.com> --- Changelog ========== Changes in v11: - dtbinding: Restored accidently deleted characters in previous revision - Link to v10: https://lore.kernel.org/r/20240813-adp5588_gpio_support-v10-0-aab3c52cc8bf@analog.com Changes in v10: - Corrected changelog ordering - Changed dtbinding commit to clarify all changes are made in software. The commit message now also expands on what the desired pure gpio mode is - Added acquired tags to commits - dt-binding: Removed multiple blank lines before the dependecies block Removed excess headers included in dtbinding example Removed constraint being repeated in free form text Merged outlying dependency into a single block - Link to v9: https://lore.kernel.org/r/20240806-adp5588_gpio_support-v9-0-4d6118b6d653@analog.com Changes in v9: - Added dt-binding dependency for interrupt-controller. Now if interrupt-controller is specified, interrupts must be provided. - Link to v8: https://lore.kernel.org/r/20240704-adp5588_gpio_support-v8-0-208cf5d4c2d6@analog.com Changes in v8: - Fixed indentation in document example (removed extra spaces) - Link to v7: https://lore.kernel.org/r/20240704-adp5588_gpio_support-v7-0-e34eb7eba5ab@analog.com Changes in v7: - Fixed commit subject for transported patch - Driver now does not setup gpio_irq_chip if interrupt has not been provided - Fixed indentation for dtbinding example - Link to v6: https://lore.kernel.org/r/20240704-adp5588_gpio_support-v6-0-cb65514d714b@analog.com Changes in v6: - Restored functionality to register interrupts in GPIO mode(i.e, these are optional but not exclusive to keypad mode since even in pure gpio mode, they can be used as inputs via gpio-keys) - Updated dt-bindings such that each keypad property depends on the others. Interrupts, although optional are now required by keypad mode but are not limited to it. - Link to v5: https://lore.kernel.org/r/20240703-adp5588_gpio_support-v5-0-49fcead0d390@analog.com V5: - Removed extra property "gpio-only", now pure gpio mode is detected via the adbsence of keypad specific properties. - Added dependencies for keypad properties to preserve the original requirements in case a pure gpio mode is not being used. - Added additional description for why the "interrupts" property was made optional - Rebased current work based on https://lore.kernel.org/linux-input/ZoLt_qBCQS-tG8Ar@google.com/ - Link to v4: https://lore.kernel.org/r/20240701-adp5588_gpio_support-v4-0-44bba0445e90@analog.com V4: - Added dt-bindings patch V3: - Moved device_property_present() for reading "gpio-only" into adp558_fw_parse() - Added print statements in case of error V2: - Changed gpio_only from a local variable to a member of struct adp5588_kpad - Removed condition from adp5588_probe() to skip adp5588_fw_parse() if gpio-only specified. adp558_fw_parse() now handles and returns 0 if gpio-only has been specified. - Added a check in adp5588_fw_parse() to make sure keypad properties(keypad,num-columns and keypad,num-rows) were not defined when gpio-only specified --- --- Dmitry Torokhov (1): Input: adp5588-keys - use guard notation when acquiring mutexes Utsav Agarwal (2): Input: adp5588-keys - add support for pure gpio dt-bindings: input: pure gpio support for adp5588 .../devicetree/bindings/input/adi,adp5588.yaml | 38 ++++++++-- drivers/input/keyboard/adp5588-keys.c | 86 +++++++++++++--------- 2 files changed, 83 insertions(+), 41 deletions(-) --- base-commit: 1c52cf5e79d30ac996f34b64284f2c317004d641 change-id: 20240701-adp5588_gpio_support-65db2bd21a9f Best regards,
